Ноооооооооооооооооооооооомер6 и 8

Answer 1

Ответ:

5/7 и 3/4

5/7 • 3/4 = 15/28

5/7 : 3/4 = 5/7 • 4/3 = 20/21

5/7 + 3/4 = 20/28 + 21/28 = 41/28 = 1 13/28

5/7 - 3/4 = 20/28 - 21/28 = - 1/28

5/8 и 3/4

5/8 • 3/4 = 15/32

5/8 : 3/4 = 5/8 • 4/3 = 5/2 • 1/3 = 5/6

5/8 + 3/4 = 20/32 + 24/32 = 44/32 = 1 12/32 = 1 6/16 = 1 3/8

5/8 - 3/4 = 20/32 - 24/32 = - 4/32 = - 1/8
